How to convert fahrenheit to celsius
Fahrenheit is the everyday temperature scale in the United States, while Celsius is the global standard for science, medicine, and most national weather services. Converting between them requires both multiplication and an offset — unlike simple unit conversions for length or weight.
Formula: °C = (°F − 32) × 5/9. Example: 68°F = (68 − 32) × 5/9 = 20°C. A fever of 101.3°F = (101.3 − 32) × 5/9 = 38.5°C. Oven at 350°F = (350 − 32) × 5/9 = 176.7°C.
Travelers, cooks using American recipes abroad, and HVAC technicians servicing imported equipment all need this conversion. A cold winter day at 14°F = −10°C.
Quick estimate: subtract 30 from Fahrenheit and halve the result. 86°F − 30 = 56, ÷ 2 = 28°C (exact: 30°C).

Subtract 32, then multiply by 5/9. Example: 98.6°F → (98.6 − 32) × 5/9 = 37°C.
0°C = 32°F — the freezing point of water.
Fahrenheit's zero was based on a brine mixture, not water's freezing point. The 32°F offset aligns the two scales at water's freeze/melt point.
